This experiment was conducted to determine the effects of time and rate of nitrogen fertilizer (urea) application on yield and yield components and quality of sunflower (Helianthus annuus L. )cv.Euroflor. A field experiment was carried out at College of Agriculture, Shiraz University during Summer 2009. The experimental design was a factorial based on a randomized complete block design with 3 ...
Field study was conducted in order to evaluate the efficacy of new herbicide quinclorac to control barnyardgrass and bulrush, the most important weeds of paddy rice. Treatments consisted of rice cultivars (Hashemi and Khazar) and quinclorac rates (50, 100, 200 and 400% the recommended dose), recommended dose of butachlor and quinclorac, each alone and plus bensulfuronmethyl (BSM), weedy and han...
the treatment of in completely formed pulpless teeth has presented considrable problems. these teeth have wide open apexes and the walls of the root canal diverge toward the apical tissues. mechanical preparation cannot be done in the normal manner beacause of the large initial size and the taper of apical part of the canal , a mechanical stop cannot be produced at the apex of the canal and , t...

Botanic determined by transects at beginning experiment. rotational alternate...
The paper tackles the problem of making direct payments in the EU countries more equal. Two sets of indices and their evolution are being presented: payment rates per product and per hectare of eligible area. The need of redistribution of direct payments is being stressed, followed by the discussion on different scenarios of distribution among Member States. The model finally accepted by the EU...
The main purpose of this study is to investigate the quantitative and qualitative characteristics of dominant tree species and their regeneration status in the Arasbaran forests. Data were collected by transect sampling and regeneration was assessed by plot with an area 100 m2. In the sample plots, we recorded information on species type, diameter at breast height, height, quality of seedlings ...
• The average annual economic loss due to OJD infection on farms was $7.68 per DSE or $65.92 per hectare. These figures represent the cost of premature sheep deaths, and lost wool and lamb production. There was substantial variation between farms, with some properties losing as much as $244.80 per hectare. Losses due to trading restrictions and variable input costs have not been included in the...
This paper examines the possible impact of climate change on Malaysian rice production. Using the Ricardian Method and farm household data, we have examined the effects on rice producers focusing on sharecropper adaptations and ecological causes. The principle goal of this research paper is to investigate the impact of climate variables such as temperature, rainfall and precipitation on rice pr...
Depeneding on the quality and quantity of herbicides and their mode of action and soil type, the number of different groups of microorganisms in soil increased or decreased. Sulphonylurea herbicides belong to a group of pesticides which in doses of only a few grams per hectar are sufficient to control weeds. The mode of action of these herbicides is based on blocking the enzyme acetolactate syn...
in order to study the tolerance level of different wild barley (hordeum spontaneum) populations to clodinafop propargyl (topic®), a pot dose response experiment was conducted in a completely randomized design with three replications at ferdowsi university of mashhad greenhouse in 2009. cultivared barley (hordeum vulgare) and three wild barley populations (shiraz, boshroyeh, and torogh) were stu...
